' Patented Nov. 22, 1938 PATENT OFFICE COFFEE MAKER HANDLE Walter R. Weeks, Hamden, Com, assignor to General Electric Company, a corporation of New York Original application September 25, 1935, Serial No. 42,007. Divided and this application April 28,1936, Serial No. 76,771

3 Claims.

This invention relates to coffee makers and it has for its object the provision of an improved handle structure in adevice of this character.

More specifically, this invention relates to coffee makers which are provided with a lower bowl and an upper bowl, together with a tube projecting from the upper bowl into the lower bowl so as to connect the two bowls together. A filter upon which the coffee grounds are placed is supported in the upper bowl over the mouth of the tube. In the operation of cofiee makers of this character, water is placed within the lower bowl and is heated. The pressure of the water vapor and air above the water level forces the water up through the tube into the upper bowl where the coffee is steeped or infused. When the heat is removed from the lower bowl, the water vapor in the lower bowl condenses and the pressure is thereby reduced sufficiently to cause the coffee infusion in the upper bowl to return through the filter to the lower bowl. After this,

the upper bowl is removed and the infusion may then be poured from the lower bowl. 1

This invention has asone of its objects the provision of an improved handle construction for the lower bowl, whereby the lower bowl may be manipulated to pour the coffee brew from the bowl.

In accordance with this invention, in one form thereof, the handle construction comprises a pair of substantially semi-circular rigid members arranged to embrace opposite sides of the neck of the lower bowl that receives the tubular member attached to the upper bowl. These members are provided with arms extending from the 35 neck in substantially parallel relation with eachother, and which are arranged to clasp a portion of a, hand-grasping member between them. This grasping member preferably is provided ,with recesses to receive the parallel arms on the neck grasping portion so as to effect an interlock connection between the handle and the neck grasping portion.-

This application is a division of my co-pend- 5 ingapplication Serial No. 42,007, filed September 25, 1935 and assigned to the same assignee as this invention.

For a more complete understanding of this invention, reference should be had to the accom- 50 panying drawing in which Fig. l is a vertical ele- 'vation of a coffee maker embodying this invention, portions being broken away so as to illustrate certain details of construction; Fig. 2 an enlarged sectional view taken through the line 55 2-2 of Fig. 1 and looking in the direction of the 'arrows; and Fig. 3 is a sectional view of a part of the handle structure used in the coffee maker of Figs. 1 and 2.

Referring to the drawing, this invention has been shown in one form as applied to a coffee makes comprising a lower water heating vessel or bowl I and an upper coffee infustion or steeping vessel or bowl ll. The lower bowl l0 is provided at its upper portion with an upright neck l2 within which a depending tubular extension l3 provided at the lower portion of the upper bowl H is. received. A suitable gasket I4, preferably formed of rubber, is inserted in the neck l2 of the lower bowl and is provided with a centrally arranged aperture to receive the extension l3 provided on the upper bowl H.

The extension l3 merges into a downwardly tapered tubular member l5, which co-operates with the extension l3 to provide a funnel connection between the lower bowl l0 and the upper bowl ll. Preferably and'as shown, the extension l3 and the tapered tube l5 will be formedintegrally with the upper bowl H, and preferably these members will be formed of glass. It is also preferable to form the lowerbowl l I] of glass.

Resting on the bottom wall of the upper bowl ll directly above the opening into the extension I3 is a filter or strainerdevice IS. The filter is secured to the upper'bowl It by means of a spring member [1, as fully described in my above-mentioned co-pending application.

The handle structure for the lower bowl arranged in accordance with this invention comprises two substantially semi-circular rigid members l8 and I9 which are arranged to be positioned on opposite sides of the neck l2 of the lower bowl, as clearly shown in Figs. 1 and 2. Preferably, a rubber collar I911. will be positioned about the neck I! so as to be interposed between the neck and the clamping members l8 and IS. The adjacent ends of the clamping members l8 and IS on one side of the neck are provided with outwardly extending arms 20 and 2| respectively,

which are arranged in substantially parallel relation with each other, as clearly shown in Fig. 2. The arms 20 and 2| are arranged to clamp between them a suitable hand grasping portion 22 of the handle structure. The handle 22, as shown, is provided with a portion 22a which is sandwiched between the two arms 20 and 2| of the neck grasping part of the structure. This portion 22a of the handle is provided with lateral recesses 23 on its opposite "sides for receiving the arms 20 and 2|, as shown in Figs. 1, 2 and 3. Preferably, inturned end portions 24 and 25 are 'lhetwoarmsllandllareflgldlyalaspedto lid ll isprovlded iorthe upperbowl II.

In the operation of the device, it will be understood that mice groimds (not shown) will be placed in the'upper bowl on the filter I, while asuitablequantityofwaterwillbeplacedinthe water heating bowl ll. After the coiiee and water have been heat is applied to the lower bowl by means oi! the stove ll so as to bring the water placed therein substantially up to the boiling point. The water vapor that is generated above the level of the water and also the heated air above this level will eventually generate a presure suiiiciently great to cause water in the lowerbowltobeforcedupthmughthetube lland extension l3 and through the iilter II into the upper bowl I l where the coffee grounds are placed. As long as the heat is applied the water will continue to flow into the upper bowl until all of the water in the lower bowl above the level of the lowerendofthetube l5 willbeforcedintothe upper bowl. The water will remain in the upper bowl to infuse the coiiee until the heat is removed to permit the lowerbowl to cool. After this happens, the water vapor in the lower bowl will condense and'thereby reduce the presure therein sufliciently to cause the coiIce brew in the upper bowl to flow down into the lower bowl through the mice grounds and the filter by at mospheric pressure and gravity. After the coilee has been made, the upper bowl is removed and the coiIee brew may be poured from the lower bowl by means of the handle 22. 7

While I have shown a particular embodiment of my invention, it will be understood, of course, thatldonotwishtobe limited thereto since many modimations may be made, and I, therefore, contemplate by the appended claims to cover any such modifications as fall within the true spirit and scope of my invention.

WhatIclaim as new and desire to secure by Letters Patent of the United States, is:

1. In a coilee maker and the like having a bowl provided at its upper end with an upright neck, a handle for said bowl comprising a member adapted to embrace said neck and having substantiallyparallel clamping arms at one side oi said neck. said arms having portions inturned toward each other at their ends remote from the neck, a grasping member having a portion arranged -to be received between said arms, said portion having recesses in its sides to receive said arms and deeper'recesses at the ends of said first recessm remote from said neck toreceive said inturned ends of said arms, a: screw fastening deviceiocated between said intumed ends and said neck pased between said arms clamping them to the portion of said grasping member between said arms and said portion having asubstantially semi-circular recess receiving said screw fastening device in interlocking relation with it.

3. In a coffee maker and the like having a bowl provided with a. neck, a handle construction comprising a grasping member, a member arranged to embrace said neck, said member having substantially parallel clamping portions at one side of said neck arranged to sandwich said grasping member between them, said grasping member having recesses in its side walls for re ceiving said parallel portions, and deeper recesses at the ends of said first-named recesses, and the ends of said clamping portions remote from said neck being turned inwardly and received in said deeper recesses, and a single fastening device located between said inturned ends and said neck passed between said arms and clamping them to the grasping member.
